Abstract

An arrangement for simulating force effects of a vehicle wheel has a multi-part housing and a frame-shaped wheel adapter mounted on the housing and arranged in a vertical plane. The wheel adapter defines a wheel center and a ground contact point of the wheel in the vertical plane. A first push rod is articulated on the wheel adapter and extends in a horizontal plane intercepting the vertical plane at the wheel center. It simulates a first longitudinal force. The wheel adapter has a U-shaped cutout near the ground contact point which is penetrated by a vertical bolt extending in the vertical plane through the wheel center and the ground contact point and connected by a first joint to the housing. A second push rod is connected to the housing transversely to the vertical plane. The axis of the second push rod intercepts the ground contact point and simulates a lateral force. A third push rod is rotated 90° to the second push rod and has an axis extending in the vertical plane through the ground contact point. It simulates a second longitudinal force and is connected by a second joint to the housing. The first and second joints have center points coinciding with the ground contact point. A force introduction member is articulated coaxially on the vertical bolt below the U-shaped cutout on the wheel adapter.

In an arrangement for simulating force effects on a wheel of a motor vehicle resulting during vehicle operation, the arrangement including a wheel adaptor having a U-shaped cutout, the wheel adaptor being connected through a first joint to a second push rod configured to simulate a lateral force, and to a rod-shaped force introduction member configured to exert a vertical force, wherein the force introduction member extends essentially vertically underneath the cutout, a third push rod configured to simulate a first longitudinal force being coupled to a second joint, wherein the first and second joints have center points which coincide with each other, the improvement comprising

the wheel adaptor being frame-shaped and extending in a vertical plane, and the wheel adaptor being articulated to a first push rod configured to simulate a second longitudinal force, wherein the first push rod extends in a horizontal plane which intersects a center point of the wheel;
the cutout being located in an area of a wheel contact point which coincides with the center points of the first and second joints, wherein a vertical bolt extends through the cutout, wherein the vertical bolt extends with a longitudinal axis thereof in a vertical plane extending through the wheel contact point and the center point of the wheel;
the vertical bolt being coupled through the first joint to a multi-part housing, the housing being rigidly connected to the second push rod, wherein the second push rod extends with a horizontal longitudinal axis thereof through the wheel contact point, and wherein the housing is coupled through the second joint to the third push rod, wherein the third push rod is rotated by 90° relative to the second push rod and extends with a longitudinal axis thereof in the vertical plane and through the wheel contact point;
and
a longitudinal axis of the force introduction member extends coaxially with the longitudinal axis of the vertical bolt.
